Treyarch has announced that Call of Duty: Black Ops 2 will once again be free to play on Steam this weekend for anyone who hasn't had a chance to check out the game.
The promotion will be going live until Sunday, giving players a chance to test out the game with no obligation to buy. This can be a great opportunity to test drive one of the most popular games of 2012 and see what all the rage is about.
Alongside this sale, Treyarch has discounted the game on Steam to $40.19, 33% off the normal price. The sale only lasts until Sunday, so if you enjoy the game bear in mind that the sale is for a limited time only.
